Building user-space audit

I'm trying to build the user-space part of the Linux Auditing Framework in https://github.com/linux-audit/audit-userspace. First, the README tells me to "see the README-install file" for building instructions and there is no such file. Second, I tried the standard build procedure using autotools: aclocal; autoconf; automake; ./configure; make ./configure fails with the following error message: configure: error: zos remote support was requested but the openldap library was not found - Is there any out-of-the-box way to build a *minimal* auditd for the x86_64 platform or I'd need to remove non-essential features such as zos remote support manually (in this case, removing it from configure.ac) ? - If there is not, where are the build dependencies documented? Thanks in advance.
